Instead of exporting a ton of data from another forum, I will simply add the following:
Cubensis do not produce laccase, if they do it's very little, whereas species armed with laccase will germinate and grow out using lignin, and other similar materials.
These materials, are also known as plant extractives (water soluble), being soluble makes it "quick" and "easy" to utilize, lignin can cause contamination.
Additionally the absence of the tea and extractives, reduces contamination to, none seen for over 6 months, semi exposed, 100% cellulose.
Spores should not germinate on complex cellulose, even enriched, alone, "quick" carbon must be present to do so.
Cubensis germinates best on cellulose, when minimal levels of sugar or starch (both quick), are present.
Cellulose compatible bacteria, will generate solubles via digestion, can trigger germination.
